摘要：
In this paper, the temperature field and stress field of a certain high RCC arch dam block at different pouring thickness during construction and operation were calculated and analyzed, and the influence of different pouring thickness on stress and safety coefficient was obtained. According to the results, in the case of the concrete poured in autumn and winter, the highest temperature at the middle of working surface is 25.53 degrees C for the 1.5 m-thick warehouse layer, 27.13 degrees C for the 3.0 m-thick warehouse layer, and 27.58 degrees C for the 4.5 m-thick warehouse layer, respectively because of the relatively low outside temperature. In terms of the maximum stress and safety coefficient, they are 1.83 MPa and 1.99 in the 1.5 m-thick warehouse layer, 2.17 MPa and 1.68 in the 3.0 m-thick warehouse layer, and 2.19 MPa and 1.66 in the 4.5 m-thick warehouse layer. Therefore, it is recommended that the 3.0 m-thick warehouse layer shall be adopted in foundation constraint areas.
